I mixed 5 drops of ECX in 10 ml of base and nuked it for the very first time in my life but could not get any taste. Repeated, and let it steep for 24 hours, and still no results. Of course I never had much luck with heat steeping tobaccos anyway, including with a crockpot. Just wondering why we are experiencing different results doing the same thing. BTW it can not be my taste buds since as far as I know they are just fine....
I'm thinking the ECX might be more diluted than the Rustica so you might need to add more. There's always a possibility you got a bad batch as well. My last bottle of TFA Ry4D from WL tasted like pg with added sweetener and a little something else sort of carmelish but weak.
If you put a drop on you finger and taste it, does it taste like it should be nice and strong?
